Create directories as part of a recipe step

The function [`scripts/create_dirs.sh`](https://github.com/cytomining/profiling-recipe/blob/master/scripts/create_dirs.sh) can be added as the first step when running the profiling pipeline.

This will remove one required manual step that users (assay devs) will need to perform to process profiles.

Read scripts/create_dirs.sh and locate the recipe definition for the profiling pipeline to determine how steps are ordered. Add the script as the first step, then verify that a pipeline run creates the required directories without the manual setup.
